BTC4 [BITCOIN 4.0] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract ownership is not renounced (belongs to a wallet)

Low level call in Address.sendValue(address,uint256) (#279-285):
- (success) = recipient.call{value: amount}() (#283)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#345-366):
- (success,returndata) = target.call{value: weiValue}(data) (#349)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
